●  As a high-growth headquarters enterprise in Songjiang District, Kejian Shares attaches great importance to the enhancement of technology R&D and application capabilities. It has long-term industry-university-research cooperation with universities such as Donghua University, Tongji University, Jiangnan University, and Hainan University, and has more than 100 patents. At the same time, it has led the formulation of national and industry standards for butyl sealing materials. It has successively won honors such as the national-level specialized and sophisticated "Little Giant" enterprise, Shanghai's specialized and sophisticated enterprise, Shanghai's high-tech enterprise, Shanghai's expert workstation, Songjiang District's enterprise technology center, and Songjiang District's patent pilot enterprise.

●  To meet the needs of various industries, Kejian Shares continues to enhance its R&D capabilities and has innovatively developed "environmentally friendly automotive hot-melt damping sheets" and other "bottleneck" products. These products combine the unique properties of various materials, offering advantages such as being non-toxic, having low aldehyde VOCs, and high performance with low density. They effectively fill the gap in the automotive industry for environmentally friendly and lightweight damping sheets and are expected to replace asphalt as the mainstream product in the industry. At the same time, five "bottleneck" products co-developed with COMAC, including "high-temperature vacuum sealing tape" and "room temperature pre-vacuum sealing tape," are about to enter the mass production phase. The first batch of sealing butyl rubber developed for Huawei's 5G base stations has also been promoted for global use.
